Connecting assembly for a wireless tire pressure monitoring apparatus

Abstract

A connecting assembly for a wireless tire pressure monitoring apparatus having a main body formed to be a branch joint with a first tube, a second tube and a third tube, a penetration needle with a first vent hole being positioned at the port of the first tube; an adapter attached to an end port of the first tube; a actuating pin disposed within the first tube and the third tube; and the air nozzle screwed in the third tube, the middle part of the sleeve portion having an second vent hole in the axial direction. When the first tube is mounted on the inflation valve, the air pressure within the tire will pass through the first tube. In this way, the tire pressure detector joined to the second tube can detect the tire pressure value at any time. It is not necessary to remove the tire pressure detector on the second tube for the inflation operation. Instead, the inflation of the tire can be done via the third tube, thereby facilitating the inflation of the internal tires to a great extent.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a connecting assembly for a wireless tire pressure monitoring apparatus, and more particularly, to an apparatus that is suitable for installation on the internal tires of heavy vehicles without affecting the tire inflation operation.[0003]2. Description of the Related Art[0004]The tires of all kinds of vehicles have to be kept at a normal tire pressure. If the tire has a lower tire pressure (than 28 psi) or runs at a high temperature, the driving safety will be affected. After some time of driving, exposure to the sunlight or the fall of temperature at night, the tire may leak to some extent and the tire pressure will fall down under a normal pressure of 28 psi. It brings a potential danger for the driving safety. Particularly, if one tire of a high speeding vehicle breaks up due to the bad airtightness of the tire valve leading to the insufficient tire pressure, the result is very destructive.[...

AI Technical Summary

Benefits of technology

[0008]It is a primary object of the invention to provide a connecting assembly for a wireless tire pressure monitoring apparatus that is formed in a branch joint with a first tube, a second tube, and a third tube. When the first tube is mounted on the inflation valve, the air pressure within the tire will pass through the first tube. In this way, the tire pressure detector joined to the second tube can detect the tire pressure value at any time. It is not necessary to remove the tire pressure detector on the second tube for the inflation operation. Instead, the inflation of the tire can be done via the third tube, thereby facilitating the inflation of the internal tires to a great extent.

[0013]d) a middle tube screwed into the second threaded section of the third tube, the center of the middle tube having in the axial direction a second vent hole, the external section of the actuating pin extending from the second vent hole for a certain length such that the compression body lies against the internal side of the second vent hole by means of the spring mounted on the internal section of the compression body, thereby keeping the third tube in a closed position in the normal state.

Problems solved by technology

If the tire has a lower tire pressure (than 28 psi) or runs at a high temperature, the driving safety will be affected.

It brings a potential danger for the driving safety.

Particularly, if one tire of a high speeding vehicle breaks up due to the bad airtightness of the tire valve leading to the insufficient tire pressure, the result is very destructive.

Nevertheless, the removal is much inconvenient since the tire pressure detector 10 is disposed next to the external tire 20b and therefore only little free room is available.

In addition, it brings also difficulties to re-screw the tire pressure detector 10 in position when each inflation operation is completed.

To carry out the above-mentioned operation within such a narrow space between the internal and external tires does consume much time and cost.

This doesn't fulfill the requirement of the economic benefit.
